Description

A4000 release film is a high temperature and high elongation release film which will conform easily to the most complex curvatures. The film is capable of temperatures up to 260°C (500°F). This film will release from most resin systems and will provide a glossy finish when removed from the laminate. All standard perforations are available. Please see our perforation table in this section.

Benefits

• Good elongation and softness reduces bridging in corners resulting in less rework on resin rich corners.
• High visibility colours reduces risk of leaving film on cured parts or confusion between perforation styles.
• Excellent release from cured parts, film comes off easily and leaves a glossy finish.
